How can the surface treatment process of a garden light model accurately reproduce the metallic or stone texture of a real street lamp?

In architectural and landscape model making, the realism of details often determines the persuasiveness of the overall scene. As the finishing touch in a garden space, a garden light model not only needs to accurately reproduce proportions and structure, but also needs to convey the material language of a real street lamp through surface treatment processes—whether it's the heaviness of cast iron, the warmth of brass, or the rugged texture of a stone base. This "seeing the big in the small" texture reproduction is precisely the core skill of high-end model consumables companies.To reproduce a metallic texture, it first relies on the synergy of material selection and subsequent finishing. Many high-quality garden light models use precision injection-molded ABS or engineering plastics as the base. Although these are non-metallic materials, multiple surface treatments can simulate the characteristics of metal. For example, on lamp posts or arms, a high-gloss finish is first applied, followed by a simulated electroplating coating to give the surface a cool, luster similar to stainless steel or aluminum alloy. To achieve a vintage cast iron effect, a matte black or dark gray base coat is used, supplemented with a light brushing technique to sweep on silver-gray or copper tones, highlighting casting seams and oxidation marks to create an industrial feel of age. For products seeking even higher realism, some companies even introduce miniature metal etchings or zinc alloy die-cast parts, directly giving the model a realistic metallic weight and feel.The reproduction of stone textures focuses more on the layered expression of texture and color. The base of a real garden lamp is often made of granite, bluestone, or concrete, with a rough surface and natural color spots. In model making, the textured surface of stone is typically replicated on a plastic or resin substrate using molds. This is then combined with spraying and hand-coloring techniques: first, thin coats of multiple colors such as gray, brown, and off-white are layered to simulate the mineral grain of the stone; then, sponge patting or airbrush atomization is used to create an uneven, natural weathering effect; finally, localized aging is achieved, such as adding subtle "moss" or "water stains" to the edges to enhance the sense of integration with the environment. This "impressionistic rather than realistic" approach avoids the plasticky feel of overly detailed designs while preserving the rustic charm of the stone.It's worth noting that surface treatment is not merely visual imitation, but also an art of light and shadow interaction. High-quality garden light models adjust the coating's gloss level according to the reflective properties of the real material—metal parts reflect light moderately to capture changes in lighting, while stone parts maintain diffuse reflection to convey a sense of weight and stability. In the sand table display, when ambient light or built-in LEDs illuminate the surface, the different areas create rich transitions of light and shadow due to the variations in surface treatment, further enhancing the material's recognizability.Furthermore, the durability of the process is equally crucial. Models need to withstand transportation, assembly, and long-term display; therefore, the surface coating must possess excellent adhesion and scratch resistance. High-end products often employ a two-component clear varnish topcoat, protecting the underlying color while maintaining the required gloss level and preventing the plastic's natural color from showing through due to frequent handling.Finally, behind this ability to reproduce textures lies the company's in-depth observation and accumulated expertise in real architectural components. Designers frequently conduct on-site investigations of municipal streetlights and classical garden lamps, recording the visual changes of different materials under sunlight, after rain, and at night, and transforming this experience into mass-producible surface treatment standards. This is why a small garden light model can evoke memories and resonance with real spaces within its limited space.In conclusion, the surface treatment of garden light models is not simply about painting; it is a comprehensive technique integrating materials science, artistic expression, and engineering practice. It imbues static miniature components with the vitality of materials, making the architectural model not only "like" but also "real"—silently telling the story of light, shadow, time, and materials.
